I'm seeing some warnings coming up in GCC 13.2 (default Ubuntu). We're running 11.4 in CI, which isn't much order (2 months) in terms of release dates. @pmienk do we have an upper bound on GCC support presently?
IOW I believe that in the hardware avx512 implies avx2 implies sse4. It's not imposed by my code, they are independent flags. So I assume it's probably that way for yours.
